报错Component definition is missing display name"/>
React.memo使用报错Component definition is missing display name
函数组件使用React.memo对其进行优化时,Eslint校验报错:Component definition is missing display
const TestCom= React.memo(({ placement }) => {...
});export default TestCom;
原因:直接导出箭头函数不会给组件一个displayName
解决:
1、添加 TestCom.displayName = 'TestCom'
const TestCom= React.memo(({ placement }) => {...
});TestCom.displayName = 'TestCom';
export default TestCom;
2、导出一个常规函数,函数名为displayName
const TestCom= React.memo(function TestCom({ placement }) {...
});export default TestCom;
